Abstract
THE gamma to alpha transformation of iron is of fundamental importance in the heat treatment of steels. The face-centred-cubic gamma form, stable at high temperatures, transforms so rapidly to the body-centred-cubic alpha form below 906° C. that it cannot be preserved by quenching. Various alloying elements stabilize the gamma phase so that it may be obtained at room temperature ae a stable or metastable form.
